Export audio file?

[praneybehl]

Hi mate, Great effort, just wondering if there is an option to export the final audio as mp3/wav?

Appreciate your help. Cheers!

Hi, unfortunately there is not such feature implemented. I wanted to add it, as the app itself is quite useless without this option, however, I'm quite busy with work related tasks all the time.

I found this http://stackoverflow.com/questions/16969201/web-audio-api-scheduling-sounds-and-exporting-the-mix which might be the way to go.

@janmyler There's a library for exporting to wav (which I've used here) and a somewhat hackily converted version for mp3 (which does seem to work but might be incredibly slow for longer tracks)

Feel free to take export.coffee from my audio editor, compile it online and drop it into your project (along with the workers). From there, usage is simple:

var number_of_channels = 2;
var oactx = new OfflineAudioContext(number_of_channels, sample_rate * length, sample_rate);

start_playing(from_position, oactx);

oactx.startRendering().then(function(rendered_audio_buffer) {
    export_audio_buffer_as(rendered_audio_buffer, file_type);
});
